Swimming pool filter aids

Sparkling clarity with mineral pool filters

We are the largest producer of Diatomaceous Earth (DE) and perlite swimming pool filter aids. We produce and market our DE filter aids under the Celite® Swimming Pool and the Aqua-Cel® brand, and perlite filter aids under the brand name AquaPerl®.

Celite Swimming Pool and Aqua-Cel are both high quality, diatomaceous earth filter media, specifically designed for use in swimming pools. Diatomaceous earth is made up of the skeletal remains of tiny aquatic microorganisms called diatoms. The remains of these diatoms form deposits of diatomaceous earth that are then mined, crushed and dried to powder form, and then calcined by heating to temperatures in excess of 1,000°C.

Celite Swimming Pool and Aqua-Cel improve filter operation. They precoat fast and effectively, improving filter efficiency, removing particles down to three microns and providing optimum clarity. Both brands filter out  most potentially harmful bacteria, making pool water safer, and can also be used in sand filters to enhance clarity. Aqua-Cel is available as a handy water-soluble pouch that can be dropped directly into the skimmer, so you don’t need to worry about dust.

Our perlite pool filter aid, AquaPerl, is a low crystalline silica grade perlite, and a great alternative filter media for swimming pools. AquaPerl is made from perlite, a naturally occurring mineral that contains no chemical additives. Perlite is a natural mineral that is volcanic in origin. It is chemically inert and has a neutral pH. Perlite is lightweight, non-toxic and environmentally safe. Perlite particle sizes are carefully processed to provide optimized filtration performance.

AquaPerl can be used in both DE and sand pool filtration units. It’s tested and certified by the National Science Foundation (NSF) and has excellent precoating qualities, even in subsequent cycles. AquaPerl demonstrates excellent dirt-holding capacity and superior cake release during backwash. Although AquaPerl is only half the weight of diatomaceous earth, it can be used as a direct one-for-one replacement for DE in your filter. 

Chemically inert, non-toxic and environmentally safe, AquaPerl gives great filtration capacity, which gives the pool a sparkling clarity. Since it backwashes faster and more thoroughly, using AquaPerl means less time spent on filter cleaning and maintenance.
